Hi<br>
|
||
<p>
|
||
I recently encountered real problems out of nowhere: <br>
|
||
<p>
|
||
the xscanimage-preview crashed the whole system.<br>
|
||
<p>
|
||
to start from the beginning:<br>
|
||
<p>
|
||
hardware: Mustek Paragon 1200SP (firmware 1.02)<br>
|
||
connected to Tekram DC390 which also runs <br>
|
||
IBM SCSI-Harddisk<br>
|
||
<p>
|
||
software: SuSE Linux 5.1 with kernel 2.0.33 and <br>
|
||
Tekram DC390(T) V1.11-driver and<br>
|
||
sane0.67 using<br>
|
||
SG_BIG_BUFF=1M (thanks to Rogier Wolff)<br>
|
||
<p>
|
||
I put the system from IDE-disk to SCSI some time ago. For some time<br>
|
||
everything worked perfect, when suddenly, exactly at the end of a<br>
|
||
preview-scan the whole system froze completely (don't laugh at me).<br>
|
||
No keybord working.<br>
|
||
<p>
|
||
I had to reset and repair a more or less corrupt filesystem :-(<br>
|
||
It happend some more times, but only EXACTLY at the end of previewing,<br>
|
||
the<br>
|
||
normal scanning was fine. With option strip-height (1 or 2) enabled<br>
|
||
previewing<br>
|
||
works mostly correct, only one crash since. smaller strip-heights seem<br>
|
||
safer and color preview very unsafe (more data coming?)<br>
|
||
<p>
|
||
I have no real idea what is going on, to me it seems some kind of<br>
|
||
timing problem? The system tries to write preview-data to disk while<br>
|
||
the scanner still locks the SCSI-bus? How could this be avoided?<br>
|
||
<p>
|
||
Anybody any hints?<br>
|
||
<p>
|
||
thanks in advance<br>
|
||
<p>
|
||
Nils<br>
